HIGH ALTITUDE INSTALLATION
Your DESA direct-vent fireplace has been tested
and approved in the USA for elevations from
0-2000 feet (610 m) and in Canada at elevations
from 0-4500 feet (1372 m).
High-altitude models as indicated by the letter suf-
fix (-HA) are equipped with specific gas controls
for installation above 4000 feet.
IMPORTANT
: Fireplaces when factory equipped
for use at high-
altitude can not be converted for use with Pro-
pane/LP gas. When installing a non-high altitude
fireplace at an elevation above 2000 feet (610 m)
(in the USA), you may need to decrease the input
rating by changing the existing burner orifice to
a smaller size. Reduce input 4% for each 1000
feet (305 m) above sea level. Check with your
local gas company for proper derate procedure
and orifice size.
When installing this fireplace in Canada at an
elevation above 4500 feet (1372 m), Check with
local or provincial code authorities.
Consult your local gas company to help determine
the proper orifice for your location.
For assistance with any high altitude installation
contact DESA’s Customer Service Department at

CHECK GAS TYPE
Use proper gas type for the fireplace unit you are
installing. If your gas supply is not correct, do not
install fireplace. See retailer where you purchased
the fireplace for proper fireplace according to your
gas type or to purchase gas conversion kit (see
Accessories, page 45).
INSTALLING GAS PIPING TO
FIREPLACE LOCATION
WARNING: A qualified
service person must connect
fireplace to gas supply. Follow
all local codes.
CAUTION: For propane/LP
units, never connect fireplace di-
rectly to the propane/LP supply.
This heater requires an external
regulator (not supplied). Install
the external regulator between
the fireplace and propane/LP
supply.
Installation Items Needed
Before installing fireplace, make sure you have
the items listed below.
• external regulator (supplied by installer)
• piping (check local codes)
• sealant (resistant to propane/LP gas)
• equipment shutoff valve *
• test gauge connection *
• sediment trap
• tee joint
• pipe wrench
• approved flexible gas line with gas connector
(if allowed by local codes)
* A CSA design-certified equipment shutoff
valve with 1/8" NPT tap is an acceptable alterna-
tive to test gauge connection. Purchase the CSA
design-certified equipment shutoff valve from
your retailer.
For propane/LP connection only, the installer must
supply an external regulator. The external regulator
will reduce incoming gas pressure. You must reduce
incoming gas pressure to between 11 and 14 inches
of water. If you do not reduce incoming gas pres-
sure, fireplace regulator damage could occur. Install
external regulator with the vent pointing down as
shown in Figure 49, page 27. Pointing the vent down
protects it from freezing rain or sleet.
